The offered Security Equipments are used to
prevent the entry of unauthorized persons into protected spaces, to keep out
undesired objects and substances, and to sound warnings when dangers threaten a
person, family, or larger group. The DVR or NVR is mainly designed to store the
security camera footage. Without DVRs or NVRs, IP cameras can still work
independently as standalone surveillance devices, just like the security
cameras with SD card. The offered Closed-circuit television (CCTV), also known
as video surveillance, is the use of video cameras to transmit a signal to a
specific place. The Security Equipments are very safe.
